CONTROL SYSTEM
A. Solenoid Connection
The hydrometer receives commands from the controller or control center via an external solenoid
valve. The hydrometer may be ordered with a factory installed solenoid valve or connected to an
solenoid valve supplied by the user.
To connect to a factory installed solenoid:
1. Connect the electric cable from controller to the attached solenoid valve. Position
the three-way selector in the “Auto” position - in this position the hydrometer will be
controlled by the solenoid.
B. Electrical Output
The hydrometer supplies volume and flow rate data to a controller or to an external measuring
device via an electrical connection. A reed switch transducer is factory installed in the register
dial. The cable attached to the reed switch transducer attaches to the controller or measuring
device.
To connect the hydrometer to the controller or measuring device:
1. Install an appropriate connector onto the bare end of the cable exiting from the reed
switch. Refer to the user manual of the controller or measuring device for details
regarding the specific connector type.
2. Connect the cable to the input port of the controller or measuring device.
